CHARLES ROSENHEIM 'ANDeEoneEs .MoMBEL,' or BRUSSELS, BELGIUM.

Be it known thatwe, CHARLES ROSEN- HEIM, englneer, residing -at 64l Rue Rubens,

and GEORGES MoMBEL, trader, residing at 33 Rue Saint-Lazare, Brussels', in the Kingdom l of Belgium, subjects of the King of Belgium, y have invented newA and useful Improvements out and ascertained in IRelating to Transom-Lifters, of which the following is a clear, full, and exact de- .sori tion.l

T is invention relates to improvements in a combined locking and operating device for transorns.

The invention. consists, generally, of a reciprocating transom-rod operatively connecte with devices for opening and closing the transom, together with a controlling device yfor operating said rod, the latter also being operatively connected with a locking device,

whereby the transom may be locked when closed, said devices being associated in amanner to permit the transom to be opened and closed without being locked.

The invention wi l be more fully described Iin connection with the accompanying drawings, and will 'be more particularly pointed tical sectional view of an improved controle ice or. iefanom-o. `iff.4isa lindv f tl trs rd li,j

fragmentary elevation of a portion of the transom and casing, showing the improved locking device. Fig. is a detail view of one portion of the operating device connected with the transom.

Like characters of reference designate similar parts throughout the dillerent figures of the drawings.

First describing the operating devices as shown in Fig. 1, the same desirabl y consist of the following parts: .The transom 18 is provided on its opposite sid es with slotted guide-i plates 22, provided with flanges .23, adapted to' be secured to the transom. The slots in A said guides are of uniform size throughout,

the upper ends of the guides and are enlarged at their'lower ends 38, provided with springs 24, which are secured l at their upper ends and are free at their lower Specieatin'of Letters Patent. Application nea lambert, 1904. serai No. 235,593.

endsv and which normally flex outwardly.

Above thetransom and mounted in bearings' 17 there is provided a rock-shaft 16, to which are rigidly secured arms 19 and 20. Said providedI on .their lower endswith pins 21, adapted to 'project through the slotted outward position in said slots. The transom 18, as shown, is hinged to the casing at its lower side and as the shaft 16 is'rocked forces the arms 19 and 20 outwardly, as

showindoaedlinesinrig.the inszitraveling back and forth in said gui es. Rockshaft 16 is provided between the arm 20 and its bearing 17 with a crank 15, Which'latter is connectedby a link 28 with a reciprocating transom-rod 14. Said rod is` reciprocated vertically by means of a controlling device, which, as shown in Figs. 2 and3, consists of a rammed ocaso, 190e.

guides 22 and to be engaged bythe springs 24 to hold the pins normally in an horizontally-disposed threaded shaft 3, carrying on its outer end a main wheel 4, and journaled in the inner and outer Walls of a metallic casing 11, which incloses the controlling device and is secured to the casing. The upper end of said casing 11 is provided with an openingto receive the lower end of the ltransom-rod 14, which carries on its lowerv vend jaws 37. A bell-crank lever provided with arms 9 and l2 is pivoted at 1() in said casing and is operatively connected with the 1 transom-rod and shaft 3 in the following manner: A roller 13 is mounted upon the arm 12 and fits snugly between the jaws 27 of the transom-rod, and the arm 9 engages a nut 6, provided with lateral projections 7, said arm being bifurcated, the-ends 8 fitting be.- tween the projections By reference to Fig. 3 it Will be seen that as the hand-wheel 4 is rotated in opposite directions the shaft 3 will cause the transom-rod -14 to travel up and down and open and close the transom.

By reference to Fig. 5 it will be noted that vthe enlargements 3S permit a slight extra play of the lpins 421, which movement will permit the transomrod 14 and the arms 19 l and 20 to be moved slightly prior to actual opening of the transom and subsequent to the closing thereof, theY purpose of which will now be described. On the upper portionof the transom 18 is provided a locking-plate 36, which projects some distance above the transom and engages a portion of the transom-casing. AA lock-bar 35 is provided which is guided at one end through a loop 39 IIO I y the arms 219 and after the transorni's and is adapted for engagement withthe prov@acting portion oftheip' ate-.36. .Said'baris plvotally mounted at' its opposite end to a bar 31, which in turn is pivoted at u pon a guide 29. Said' bar 31 is provided with a longitudinally-disposed slot 33,inclined outwardly at its lower end and through which a pin 32 on the upper end of the transomrod i 14 projects.- It will be obvious 'that when thef-transom is closed, as shown in Fig. 4,;and'

'the Apins occupy -an outward position in :the
